Abzû is an adventure video game developed by Giant Squid Studios and published by 505 Games for PlayStation 4 and Microsoft Windows. Its name derives from the ancient words "ab" (ocean) and "zu" (to know), intended to be interpreted as "ocean of wisdom". This is analogous to Abzu, the ancient Mesopotamian name for the religious concept of a primeval sea. Papercraft designed and created by Paperized Crafts.
